Tumors in the lungs, liver, pancreas, kidney, prostate and more, can move as much as two inches with every breath. These movements often occur because of normal breathing or other regular bodily functions, such as the passing of gas or filling of bladder. When treating such tumors with radiation therapy, it can be difficult to accurately target these tumors without damaging surrounding tissue and organs.
There are techniques employed to help to minimize these movements during treatment. Some of these techniques include:
While these techniques can be effective depending on the patient and form of treatment, they can also be problematic and painful for many patients depending on their age, health, and other factors.
There is another option for patients seeking radiation therapy: the CyberKnife System. Treatment with CyberKnife is completely non-invasive and is able to deliver high doses of radiation with extreme precision from a variety of different angles. CyberKnife is also the only radiotherapy system that is able to track the tumor’s movements during treatment and adjust accordingly in order to minimize exposure to surrounding organs and tissue, without the requirements of breath holding, gating or abdominal compression.
The intelligent and highly advanced software of the CyberKnife combined with image guidance; detects the treatment site, follows the movement, verifies it is on target, and corrects to be on target when it is not, all before each radiation beam is delivered.
Treatment with CyberKnife is completed within 1-5 treatments; it can be used as the primary treatment or in conjunction with other treatments, such as chemotherapy, conventional radiation therapy or surgery. Due to its extreme precision, the CyberKnife was originally developed for treating brain tumors. In 2001 the FDA approved CyberKnife for the treatment of cancerous and noncancerous tumors found throughout the body, including:
